Ink-fountain-roller lifter.



WILLIAM EBEN AND WILLIAM CALDWELL, OF CHICAGO, ILLINOIS.

INK-FOUNTAIN-ROLLER LIFTER.

Specification of Letters Patent.

Patented Dec. 16,1913.

Application filed May 19, 1913. Serial No. 768,613.

To all whom it may concern:

Be it known that we, WVILLIAM EBEN and VILLIAM CALDWELL, citizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Ink-Fountain-Roller Lifters, of which the following is a specification.

Our invention relates to devices for lifting the ink roller from ink feeding fountains of printing presses and the like.

The object of this improvement is to provide a simple and effective means for raising the ink roller bodily out of the ink trough for pur oses of cleaning, repairing and the like without changing the feeding adjustment of said fountain.

Other objects will-appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure 1 is an elevation of the end of an ink fountain equipped with our invention, Fig. 2 is a side elevation of the same, Fig. 3 is a fragmental section of one of the lifting elements used in the construction, and Fig. 4 is a side elevation of an ink fountain equipped with a slightly modified form of lifting mechanism.

The preferred form of construction as illustrated in the accompanying drawing comprises an ink fountain of conventional construction comprising side pieces 5 connected by a supporting plate 6, having a bottom plate 7 and an ink roller 8. The sides 5 are preferably divided as indicated by line 9 in a manner to provide a divisible bearing for the journals 10 of the ink roller 8 so that upon removal of screws 11 the upper portion of sides 5 maybe removed to permit the removal of ink roller 8 from the ink trough, I j

Qur improvement consists .in providing lifting mechanisms at the ends of said ink roller 8 and. connecting them, to operate in unison to lift the ,ink roller from its lower to 1t s upper positions,,iiidicated in Figs. 2

4. The preferred form of lifting mechan sm. comprises a lifting member at each end of the ink roller and each lifting member compr ses a curved supporting head 12 carried on the upper end of rack bar 13 and said rack bar passes through supporting plate 6 and slidably mounted in a frame 14 carried on the under side of plate 6. The frame 14: is provided with an enlargement in which is housed a gear 15 which meshes with rack bar 13. The two gears 15 of the lifting elements are connected by means of a shaft 16 to cause simultaneous operation thereof. On the end of shaft 16 is provided a crank 17 by means of which operation of the elements is effected. Pivotally secured on plate 6 are pawls 18 which engage the teeth of rack bars 13 to support the roller 8 in its elevated position after having been raised from the ink trough.

In the modified construction shown in Fig. 1, a shaft 19 is rotatably mounted on the frame 20 of a printing press or the like and secured near each end thereof are arms 21. The arms 21, one of which is shown, are each provided with sockets 22 adapted to raise the roller 8 upon rotation of the shaft 19, as will be readily understood. The shaft 19 is provided with a crank arm 23 by which the shaft 19 is manually operated.

In operation, when it is desired to clean the fountain or repair it, it is always desirable to remove the roller or the feeding plate 7 of the fountain in order to efiect such cleaning or repairs. When the plate 7 is removed it is always necessary to loosen screws 24 to permit the plate 7 to be loosened and since the screws 24 are all set at certain positions in order to effect the proper feeding of ink from the fountain, any change made in their adjustment causes considerable readjusting after the cleaning or repairing of the fountain has been accomplished. We, therefore raise the ink roller 8 from the ink trough without altering the adjustment of plate 7. In this way considerable time and trouble are saved. In order to raise the roller 8 itis only necessary to remove screws 11 and the upper portions of sides 5 and operate the lifting elementsby means of crank 17 01123 to raise the roller 8 to its upper dotted linepositions, as indrf cated in Fig. 2 or 4, and after the repairs or cleaning has been completed the roller 8 is lowered to its normal position by means of the crank 17 or 23 and the sides and screws 11 readjusted to their positions to place the device in operative condition again.

While we have illustrated and described the preferred forms of construction for car ourselves tothe precise details of construction set forth but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.

Having Patent is:

A clevice of the kind described comprising a frame; an ink trough'on said frame; an ink rollerajournaled in said ink trough and having its supporting shaft projected be-; yond the ends of said trough; vertical rack bars, each having a socket at its upper end engaging one ofthe projected ends of said support ng shaft; a spur gear meshing with each rack bar; a manually operative shaft 1: carrying said spur gears; and guide casings guiding said rack bars and inclosing said spur gears ,v substantially as described.

Copies of this patent may be obtained for jive cents each, by addressing the Qom nissioner of late nts.

T sa d upp rt described our invention what we" claim as new and desire to secureby Letters said spur gears; and

bars, substantially.

2. A device of the kind described comprising frame; an ink trough on said frame; an ink roller journaled in said ink trough and having its, supporting ishaftvprojected beyond the ends of *s aidtrough; vertical rack bars, each having a socket at its upper end engaging one of the projected ends of shaft; a spur gear meshing With each rack bar; a manually operative shaft carrying said spur gears; guide casings guiding said rack bars and inclosing pawls pivoted on said frame and lockingly engaging said rack as described; r v In testimony/whereof we have signed our names .to this specification in the presence two subscribing witnesses.
